vfio/mdev: Correct the function signatures for the mdev_type_attributes The driver core standard is to pass in the properly typed object, the properly typed attribute and the buffer data. It stems from the root kobject method: ssize_t (*show)(struct kobject *kobj, struct kobj_attribute *attr,..) Each subclass of kobject should provide their own function with the same signature but more specific types, eg struct device uses: ssize_t (*show)(struct device *dev, struct device_attribute *attr,..) In this case the existing signature is: ssize_t (*show)(struct kobject *kobj, struct device *dev,..) Where kobj is a 'struct mdev_type *' and dev is 'mdev_type->parent->dev'.

vfio/mdev: remove unnecessary NULL check in mbochs_create() Originally "type" could be NULL and these checks were required, but we recently changed how "type" is assigned and that's no longer the case. Now "type" points to an element in the middle of a non-NULL array. Removing the checks does not affect runtime at all, but it makes the code a little bit simpler to read.
